Supermo, you may be right.. The inserts are ridged I think, if you mean with the flat bottoms being ridged. They do have the flat bottom.
BK, from what I've read, changing the pitch subtly changes the span subtly. Putting reverse pitch on a ball allows the ball to come off cleaner, and thus more revs. More revs = more hook.
If you were to add a slightly more positive pitch to the ball, then you could reduce the amount of revs and hook put on the ball.
If I am wrong here, don't be afraid to speak up. I'm not afraid of being wrong, just afraid of being wrong and then sharing flawed knowledge
